AUTOMATIC CRIMPING-MACHINE.

Specification of Letters Patent.

' Patented Dec. 26, 1911.

To all whom it may concern:

Be it known that I, ALDEN B. STARR, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in AutomaticCrimping-Machines; and I do hereby declare the following to be a full,clear, and" exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to crimping machines adapted to apply tops orbottoms to vessel bodies, and has for its object to produce a machine ofthis character, which will be more simple in construction, as well asmore efficient in action, than are the machines heretofore proposed fordoing the same work.

To these ends the invention consists in the novel details ofconstruction and combinations of parts more fully hereinafter disclosedand particularly pointed out in the claims.

Referring to the accompanying drawings forminga part of thisspecification, in which like numerals refer to like parts in all theviews. Figure 1 is a perspective view of a crimping machine made inaccordance with my invention; Fig. 2 is a sectional view taken along theline 2-2 of Fig. 1 looking in the direction of the arrows; Fig. 3 is adetail view partly in section showing the relation of the carton closurewith the crimping wheel after the first operation of the foot lever hastaken place; and Fig. 4 is a view similar to Fig. 1, showing therelation of the crimping wheel and carton closure after the finaloperation of the foot lever.

1 indicates any suitable standard or base for supporting the mechanism,and on this base is suitably mounted a shaft 2, carrying tight and loosepulleys 3 and 4, over which pass the usual belt shifters 5 and 6operated by the rod 7 provided with the handle 8, and mounted upon thebracket 9, carried by the said standard 1. The shaft 2 also carries apulley 10, which is fast thereon, and over this pulley passes a powerbelt 11. This power belt likewise passes over a horizontally disposedpulley 12, mounted on the revolving mandrel 13, and it also passes overthe guide pulley 14, mounted on the projection 15 of the standard 1. Themandrel 13 is suitably ournaled for revolution in the projections 16 and17 of the standard 1, and is provided at its lower end with acylindrical extension or head 18, adapted to enter depressions inclosures for vessel bodies.

The foot lever 20 is suitably mounted in the lower end of the standard1, as by pivoting the same at 21 to the bracket 22, and near one end isattached the coiled wire spring 23, to which is also attached as at 24,the lever 25, pivoted at 26 to the standard 1, and provided with theforked extremity 27 pivotally attached to an adjustable sleeve 28,carrying the reciprocating plunger or mandrel 29. This plunger 29 isloosely held for reciprocation in the split bearings 30 and 31 carriedrespectively by the projections 32 and 33 of the standard 1. The upperend of said plunger 29 is also provided with an extension or head 34adapted to receive a vessel body. The parts are so located that theextension sleeves or heads 18 and 34 are always in alinement, while thelatter may revolve on the ball bearings 34'.

It is evident from what has so far been disclosed, if a vessel body 35,provided with a closure 36, see Fig. 3, is placed upon the head orsleeve 34 and that if the parts are brought to the positionsillustrated, a roller or other crimping tool, such as 37 may readilycrimp or turn under the flange 38 of the closure 36, provided suitablemechanism is present to force the crimping means 37 into contact withthe flange 38. In order to automatically cause this crimping operationtotake place, I provide the foot lever 20 with the rod 40, which may bepivoted to the said lever as at 41, and this rod'40 extends upwardly toa reciprocating piece 42 to which it is pivoted as at 43. The saidmember 42 is cut away as at 44, and provided with the cam-like surface45 adapted to take against a similar surface 46 on the sliding member47, while reciprocating through the slot 48 of said member 47. The saidmember 47 carries a stud 48, mounted in the two 'aws 49 and 50, integralwith said member 4 and said stud 48 carries said crimping wheel 37, aswill be clear from the drawings. It is, therefore, evident when power isapplied to the pulley 10, belt 11, pulley 12 and mandrel 13, while theplunger 29 through a depression of the foot lever 20, is brought intothe position shown in Fig. 3, the vessel body 35 may rotate with thehead or sleeve 34 on the ball bearings 34 owing to the friction betweenthe parts. At the same time it is evident that should the foot lever befurther depressed its connecting rod 40 will cause the cam surface 45 toforce the crimping roller 37 into close contact with the flange 38 ofthe vessel closure, all as is shown in Fig. 4. The stud 48 is screwthreaded as illustrated, and, therefore, the crimping wheel 37 may beadjusted up and down to some extent as by means of the nut 55. Thesliding member 47 is mounted on an adjustable frame 56 which frame is inturn mounted upon the slides 57, 58 and 59', carried by the bracket 60integral with the frame 1. The slide 58 is screw threaded as best shownin Fig. 2, and is further supported by the bracket 62, secured to saidbracket 60. It is evident that the said frame 56, carrying the slidingmember 47 may be adjusted to and from the standard 1 by means of thenuts 63, carried by said member 58. The parts are so disposed, as bestillustrated in Fig. 2, that the said slide 47 and crimping roller 37 eX-tend in a radial line from the center of the mandrel 9, so that when anadjustment of the frame 56 takes place, the roller 37 will be moved in adirection across this radial line.

A spring is secured at one end to the slide 47, and at its other end toan upturned portion 71 of the adjustable frame 56, and consequently theroller 37 is normally held at some distance from the periphery of theclosure 36, as is best shown in Figs. 2 and 3.

The operation of my invention will be clear from the foregoing, but maybe briefly summarized asfollows: WVhen it is desired to secure an endclosure to a vessel body, the said body 35 carrying the closure isplaced upon the head or sleeve 34 of the plunger 29. Power being turnedon, the belt 11 causes the mandrel 13 to continuously rotate, and

power being applied to the foot lever 20, the yielding spring 23 throughthe lever 25, causes the plunger 29 to rise into the position shown inFig. 3, whereupon the friction between the parts will cause the saidvessel body and closure to rapidly rotate. Afurther pressure upon thefoot lever 20 will cause the spring 23 to still further yield, and therod 40 to pull down the cam surface 45 and thereupon to force thecrimping roller 37 against the tension of the spring 70 into engagementwith the periphery of the vessel closure 36. The continued spinningoperation will cause the said roller 37 to crimp in or turn under theflange 38 of the said closure 36, thereby securely holding said closurein place, as best shown in Fig. 4. After the closure is firmly appliedto the vessel body, a release of the foot lever will permit all of theparts through the action of the springs 70- and 23 to return to theirnormal positions. Of course power is applied and shut off through themanipulation of the rod 7 and handle 8.

The action of the stout coil spring 23 is important in the aboveoperation, in that it is made sufliciently strong to quickly throw theplunger 29 into its upper position, and at the same time it prevents anyharsh or forceful engagement between said plunger and the mandrel 13when grasping the closure blank 36. Further this spring 23 permits thecontinued depression of the foot lever 20 in the final advancement ofthe crimping roller 37 without producing any undue friction and loss ofpower between the parts. It is evident that those skilled in the art mayvary the details of construction and the arrangement of parts withoutdeparting from the spirit of my invention, and, therefore, I do not wishto be limited to such features except as may be required by the claims.
